plywood, ranging from smooth, natural surfaces suitable for finish work to more economical unsanded grades used for sheathing. This includes a dozencommon thicknesses (external link)and overtwenty different grades (external link). In Canada, Graded Douglas-fir Plywood (DFP) is manufactured to meet...
Sheathing:Sheathing creates a structural panel, reinforcing a shear wall so that it doesn’t collapse on itself. This layer is typically plywood or oriented strand board (OSB). Common Shear Wall Materials A shear wall can be made from a variety of materials, but the most common ones are con...

both types of trees, although this is uncommon. You can generally find softwood materials in rough carpentry and building framing, which light commercial construction industries use. Residential construction uses hardwood lumber for finished products like furniture, flooring, staircases and plywood panels...
thus lowering their cost. This is desirable for structural panels because finish plywood can be extremely expensive. The "X" indicates that the plywood can withstand some moisture exposure. As with OSB, it is suitable for exterior sheathing as well, although it is not as water-resistant as OSB...
The compact roof assembly is the standard low-slope construction method. It is very effective on steeper slopes as well. Install approximately 2” of closed-cell spray foam insulation on the underside of the roof sheathing. Ensure it adheres tightly to all rafters, roofing nails, and penetration...
Here’s a photo of one wall. Actually the other walls are already done in this picture. The right side wall as shown reveals the 1-inch foam board with a R-value of 6.5. Combine that with two layers of 1/2-inch sheathing plywood (.6 x 2) and we’re looking at a total of almo...
